GEORGE PHILIP KATO, SE, OF JERSEY (TTY, NEW JERSEY;

".BCEPRO FOB. USE IN BOOTS AND SHGES.

I '0. all whom it may concern:

Be it known that I, Gnoaen Pnnar Karo, Sn, a citizen of the UnitedStates, and a resident of Jersey City, in the county of Hudson and Stateof New Jersey, have inventedccrtain new and useful Improvements in Arch-Props for Use in' Boots and Shoes, of which the following is a secification.

The invention re ates to improvements in arch props to be placed inshoes and boots for supporting the arch of the foot, and consists in thenovel features hereinafter described and claimed.

The object of my invention is to produce a light, simple, durable andellcctive arch pro which will be comfortable to the wearer an may bereduced at com aratively small expense, an of parts and may be cleansedfrom time to time as required and thus kept in proper con dition.

In carrying out my invention 1 term my arch prop in one integral pieceof hard-rubber, pressed into sha e and so conform the '25 same that itmay fin a firm bearing in the .shoe and comfortably receive and supportthe arch portion of the foot.

The inve ition will be fully understood from the detailed descriptionhereinafter presented, reference ,being had to the arcompanyingdrawings, in which:

Figure 1 IS a top view of an arch prop embodying my inviention and of aform adapted for the left foot; Fig. 2 is a like view of a similar archprop adapted for the right foot; Fig. 3 is a bottom view of the leftfoot prop; Fig. 4 is a longitudinal section of same on the dotted linel--'l of Fig. 1; l ig. 5 is a transverse section of same on the dotte dline 5 --5 of Fig. 1. i

In the drawings, 10 designates the arch )rop for the left foot, and 11the arch prop lor the right foot. Each arr-h prop is in one integralpiece of hard-rubber and is formed in a die or mold.

vention has a longitudinally arched upper surface and at said surface isconcave trans Versely considered, and said prop broadens from the heelportion 12 toward the front .30 portion 13. At its inner side edge theprop turns upwardly, as at let, to conform to and support the foot, thisupwardly turned portion forming what may for conrcnienre be tern'ied'aflange which 13 greatest in extent along about the middle portion oi theedge Specification of Letters Patent.

l of the prop and thence narrows or becomes of less extent toward theends of the prop. At its outer side edge the prop, along said edge, ismade concave, as at 15, beyond the heel portion 12, whence said edgeextends outwardly and forwardly toward the front end of the prop.

The lower surface of. the prop is arched longitudinally and is convexalong, its side portions transversely considered. Extendinglongitudinally of the lower surface of the prop are the parallel ribs16, which are deepest at their middle portions and thence decrease indepth toward the ends of the prop. The ribs .16 bear upon the sole ofthe shoe and take much of the weight exerted upon the rep.

The prop of the general form and construction shown has provcn to be.comfortable and cllicient in use; it is in one piece of material and maybe readily applied to and removed from the shoe, and it has a smoothsurface and does not require to be covered with leather or the like, forwhich reason the prop will not become ragged in appearance and may bewashed with soap and water as occasion may require.

The prop being of hard rubber is light in wcight'and may be readilygiven an accurate initial shape, and thereafter the prop may beconformed to the special shape or width of the foot, so as to lit thesame snugly, by first subjecting the same to the proper degree of heat,then )rcssing the same to suit and then plunging the same in cold waterto set the prop to the new shape.

that it presents no parts subject to a corroding action or which areinjurious to the wearer. I r

The arch prop is provided with vertical openings 20 disposed between thevertical I planes of the ribs 16, between which an air 1 chamber isformed, whgrcb'y the region-about the prop may have proper ventilation;l What lclaim as my invention and desire to lsecurc by Letters-Patent,is:- I The arch prop hereinbefore described in l one integral piece ofmolded hard rubber, said prop having a hard smooth upper surface whichis longitiulinally upwardly arched throughout substantially its entirelength and transversely (:onravcd throughout sub slant iully its entirelength, the side edges of said prop being extended urnvardly, and the Afurther desirable feature of the prop is lower surface-ofthe same beingformed with integral ribs which decrease in depth toward the ends of t aprop to engage the sole of the sh0e and fzflcrd a durable support forthe 5' main body of the prop above said sole; substantially as sci;fog-13h.
